Description
The MLX90819 is an integrated relative pressure sensor delivering a ratiometric analog or digital (using the SENT protocol) signal.
Use of an optimized architecture and a high density CMOS technology imparts the MLX90819 with best in class automotive EMC performance. A DSP based architecture using a 16bit microcontroller provides outstanding performance in terms of initial accuracy.
FEATUREs and Benefits
